We propose a new prior distribution for classical (non-hierarchical) logistic regression models, constructed by first scaling all nonbinary variables to have mean 0 and standard deviation 0.5, and then placing independent Student-t prior distributions on the coefficients. As a default choice, we recommend the Cauchy distribution with center 0 and scale 2.5,(More)
This paper investigates the role of economic variables in predicting regional disparities in reported life satisfaction of European Union (EU) citizens. European subnational units (regions) are defined according to the first-level EU nomenclature of territorial units. We use multilevel modeling to explicitly account for the hierarchical nature of our data,(More)
AIMS AND BACKGROUND Discordance of intraoperative analysis with definitive histology of the sentinel lymph node in breast cancer leads to completion axillary lymph node dissection, which only in 35-50% shows additional nodal metastases. The aim of the study was to identify individual patient risk for non-sentinel lymph node metastases by validating several(More)

In recent years, increasing attention has been paid to household impoverishment in Italy. Most of works dealing with this issue are based on summary statistics, which do not capture the whole information contained in the income distribution. The paper applies a non-parametric tool, the “relative distribution”, to Italian household income data during(More)
This paper examines how spatial price differentials affect income distribution in Italy. The distribution of household income is “reshuffled” after controlling for the purchasing power of households residents in different regions, but only when housing price variations are included in the PPP index. Poor households living in Southern Italy alleviate their(More)
We estimate the long-run demand for broad money at the Gulf Cooperation Council area level (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates (UAE)) and at single country level over the 1980–2009 period. Applying time series and panel econometric tests, we first document the existence of long-run equilibrium relationship for money(More)
